I have an object that has coordinates [x,y], the object moves in the x-y plane. The plane is described by a circular set of datapoints, as shown in the figure below.
I wish to display the "path" the object has taken (red) , and the current location (green).
I was thinking of displaying it something like the lower image, but any other way would be usefull too.
Any suggestions? (I'm not asking for any code :), I can figure that out on my own)
